I have a 9 year old, I would never leave him in the car by himself. He also would probably not understand that puppies have smaller lungs and can't breathe in things that bigger people can. The kid was 9, that's really young IMHO and it's not a matter of knowing 'right or wrong'. How would a 9 year old know that it would be poison to a pet? They wouldn't. You spend lots of time telling your kids about drugs but not that air fresh. or shoe spray will kill pets. Heck, half of America doesn't know that if you use a teflon pan(leave it on the stove too long, it emits fumes)it may kill birds! A responsible child left in a car with a dog that pooped wouldn't think to clean it up, what would they do with it? They of course, would try to cover the smell. Some 9 year olds are not as mature as other ones.
